DUI in Nevada (NRS 484C.110): Penalties, Defenses and What to Expect
Driving under the influence is the most common criminal charge filed in Clark County, and it is also one of the most technical. A DUI case under NRS 484C.110 is built almost entirely on evidence gathered in the first hour after a traffic stop: the reason for the stop, the officer’s observations, field sobriety tests, and a breath or blood result. Each of those steps has rules, and each can be challenged.
This guide explains how Nevada defines DUI, what a first, second and third offense carry, how the separate DMV process works, and the defenses that come up most often in Las Vegas and Henderson cases.
DUI in Nevada at a Glance
| Statute | NRS 484C.110 (offense); NRS 484C.400 (penalties) |
| First offense within 7 years | Misdemeanor – 2 days to 6 months in jail (or 48–96 hours of community service), $400–$1,000 fine, DUI school |
| Second offense within 7 years | Misdemeanor – 10 days to 6 months in jail or residential confinement, $750–$1,000 fine, treatment program |
| Third offense within 7 years | Category B felony – 1 to 6 years in prison, $2,000–$5,000 fine |
| Record sealing | Misdemeanor DUI: 7 years after the case closes. Felony DUI: generally not sealable |
What the State Must Prove Under NRS 484C.110
NRS 484C.110 can be violated in several different ways. To convict, the prosecutor must prove beyond a reasonable doubt that you drove or were in actual physical control of a vehicle on a highway or on premises to which the public has access, and that at the time one of the following was true:
- You were under the influence of intoxicating liquor, a controlled substance, or a combination of the two, to a degree that made you unable to drive safely;
- You had a blood or breath alcohol concentration of 0.08 or more;
- You were found by a test taken within 2 hours of driving or being in physical control to have a concentration of 0.08 or more; or
- You had a listed prohibited substance in your blood or urine at or above the amounts set in the statute.
“Actual physical control” means a person can be charged without ever being seen driving – for example, someone found asleep behind the wheel with the engine running. Courts look at the totality of the circumstances, including where the keys were, whether the engine or lights were on, and where the vehicle was parked.
Lower limits apply to some drivers. A commercial driver is subject to a 0.04 limit while operating a commercial vehicle, and drivers under 21 face administrative consequences at 0.02. Under a 2026 change from Assembly Bill 4, the specific marijuana blood-level limits in the statute now apply to certain DUI offenses punished as felonies.
Penalties for DUI in Nevada
Penalties are set by NRS 484C.400 and depend on how many prior DUI offenses you have within the preceding 7 years. A prior that was conditionally dismissed or resolved through a specialty court program still counts toward the 7-year look-back.
| Offense | Classification | Jail or prison | Fine and other requirements |
|---|---|---|---|
| 1st within 7 years | Misdemeanor | 2 days to 6 months in jail or residential confinement, or 48–96 hours of community service | $400–$1,000; DUI school; treatment program if BAC was 0.18 or higher |
| 2nd within 7 years | Misdemeanor | 10 days to 6 months in jail or residential confinement (at least one 48-hour block) | $750–$1,000; treatment program; possible reduction through treatment under NRS 484C.330 |
| 3rd within 7 years | Category B felony | 1 to 6 years in state prison | $2,000–$5,000; possible treatment under NRS 484C.340 |
| Any prior felony DUI | Category B felony | 2 to 15 years under NRS 484C.410 | $2,000–$5,000; no 7-year limit |
Beyond the criminal sentence, a DUI conviction carries a driver’s license revocation through the Nevada DMV and an ignition interlock requirement. Having a child under 15 in the vehicle is an aggravating factor the judge must consider at sentencing, and jail time imposed for DUI must run consecutively with jail time for related offenses such as driving on a revoked license.
First-offense cases are frequently negotiated. Depending on the facts and the defendant’s record, outcomes can include a reduction to reckless driving under NRS 484B.653, which avoids a DUI conviction on the driver’s record and the 7-year sealing wait.
Common Defenses to DUI Charges
Every case turns on its own facts, but these are the issues we look at first when reviewing a charge like this one.
The stop was not legally justified
Police need reasonable suspicion of a traffic violation or criminal activity to pull a car over. If the stop was based on a hunch, a misread plate or a lawful driving behavior, everything that followed may be suppressed. DUI checkpoints also have to be run according to approved procedures.
Problems with the breath test
Breath results in Nevada come from a specific approved instrument that must be calibrated and maintained on a schedule, operated by a certified operator, and preceded by an observation period. Calibration records, operator certifications and the test sequence itself are all reviewed. Two samples that do not agree within the required tolerance are a red flag.
Blood draw and lab issues
Blood results depend on proper collection, a valid warrant or consent, chain of custody, storage and the lab’s analysis. Delays between driving and the draw also matter, especially when the State must rely on retrograde extrapolation or the 2-hour rule.
Field sobriety tests were not administered correctly
Standardized field sobriety tests are only as reliable as the conditions and instructions. Uneven pavement, footwear, weather, injuries, age and the officer’s own departures from the standardized protocol can all undercut the officer’s conclusions. Body-worn camera footage often shows something different from the report.
No proof of driving or actual physical control
If no one saw you drive and the circumstances of physical control are ambiguous, the State may not be able to prove a basic element of the offense.
Record Sealing, Immigration and Other Consequences
Driver’s license and DMV
The DMV case runs separately from the criminal case. An arrest based on a failed or refused test can lead to revocation, and the right to an administrative hearing must be requested quickly. A first-offense revocation is generally 185 days, with the option of driving sooner with an ignition interlock device; longer periods apply to repeat offenses and refusals.
Record sealing
Under NRS 179.245, a misdemeanor DUI can be sealed 7 years after you are released from custody or no longer under a suspended sentence. A third-offense felony DUI generally cannot be sealed, with a narrow exception for people who completed the statewide sobriety program. A dismissed charge can be sealed right away under NRS 179.255.
Employment, insurance and travel
A DUI conviction typically raises insurance costs (and requires SR-22 filing), can affect professional licenses and commercial driving privileges, and may make entry into Canada difficult. For non-citizens, a simple alcohol DUI is usually not a deportable offense on its own, but drug-related DUIs and repeat offenses can create immigration problems.
Related Nevada Offenses
- DUI causing death or substantial bodily harm (NRS 484C.430) – felony DUI when a crash injures or kills someone.
- Reckless driving (NRS 484B.653) – a common negotiated reduction in first-offense cases.
- Driving on a revoked license (NRS 483.560) – often charged alongside a DUI after a prior revocation.
How DUI Cases Move Through Clark County Courts
Where the case is heard depends on how it is charged. Misdemeanor versions stay in Las Vegas Justice Court or the municipal court for the city where the arrest happened (Las Vegas, Henderson or North Las Vegas). Gross misdemeanor and felony versions start in justice court and, after a preliminary hearing or grand jury indictment, move to the Eighth Judicial District Court. Because the classification often turns on facts the prosecutor must prove, such as value, injury, a weapon or a prior conviction, the early stages of the case are frequently where the most important negotiating happens.
Frequently Asked Questions About DUI in Nevada
Can I refuse a breath test in Nevada?
You can decline, but Nevada’s implied consent law means refusal leads to license revocation, and officers routinely obtain a warrant for a blood draw. Refusal can also be mentioned at trial. Whether it helps or hurts depends heavily on the facts.
Will I go to jail for a first DUI in Las Vegas?
The statute allows 2 days to 6 months, but it also permits 48 to 96 hours of community service instead of jail for a first offense. Many first-offense cases resolve without additional jail time beyond the arrest, particularly when there is no accident and the BAC is not high.
How long does a DUI stay on my record in Nevada?
For enhancement purposes, a DUI counts as a prior for 7 years. A misdemeanor DUI conviction can be sealed 7 years after the sentence is completed. It does not disappear automatically.
Can a DUI be reduced to reckless driving?
Yes, in some cases. Prosecutors consider the BAC, whether there was an accident, the strength of the evidence, and the driver’s record. Weaknesses in the stop or the testing often drive these negotiations.
